Just a caveat when you do use the NEXT-SIBLING method: In some cases you might get a handle / object back, but when you do a VALID-HANDLE or VALID-OBJECT on it it will return FALSE. It typically happens when you've created something inside a widget-pool and destroy the widget-pool later, but nowhere there is an explicit DELETE on that handle / object. Personally I think this is a bug because that should've be cleaned up as part of the widget pool, but for now you need to ignore these invalid handles / object and do another NEXT-SIBLING (yes you can do that, even though they don't point to a valid handle / object). If you don't you'll simply stop scanning the rest of the chain.
